INSTALLATION AND SET-UP
The fan is designed for wall (with the motors on ball and slide bearings) or ceiling (with the motors on ball bearings only,
L option) mounting and can be used for direct outdoor air exhaust through a round duct or a duct system. In case of
installation through a duct system, select the duct cross section in accordance with the fan size.
When installing the fan with direct air discharge outside through the wall, be sure to install a ventilation grille with louvre
shutters or a ventilation hood on the outside to prevent rainfall, snow, leaves, branches, etc. from entering the duct. To
reduce the risk of condensate forming in the duct, the space between the hole in the wall and the duct must be insulated.
Install the air duct with the minimum slope of 1...2° downwards to the outer wall side for condensate removal.
The duct system should not exceed 5 meters and have more than two bends.
During ceiling installation, vertical air discharge upwards is not allowed even if there is a protective outer hood on the roof.
10...20
In case of ceiling mounting and roof air discharge, the air ducts system must include a condensate drain (not included in
the delivery set, must be ordered separately).
Check the fan for any visible damages of the impeller, the casing and the grille before starting installation. The casing
internals must be free of any foreign objects which can damage the impeller blades.
While mounting the unit, avoid compression of the casing! Deformation of the casing may result in motor jam and
excessive noise.

ATTENTION!Thepowersupplycablesmustonlyberoutedtothelocationinthe casingspeciedbythemanufacturer.
Routing the power supply cables through an unauthorised opening will invalidate the manufacturer’s liability for
the product and void the warranty. The power supply cable must be stripped of insulation by a maximum of 8 mm.
After installation, pass this user’s manual to the end user for reading.

Units mounting is possible in zones 2 and 3, provided that the
installation and connection are performed in accordance with the
requirements of IEC 60364-7-701 (current edition), as well as in
accordance with the requirements of the national standards of the
country of installation.

12
The fan mounting sequence:
1. Cut off power supply and make sure electricity has been turned off.
2.Remove the front panel of the fan.
3.Insert the fan into the ventilation opening and mark the location of the power cable and the casing mounting points on
the wall;
4. Route the power cable to the point of entry into the fan casing and drill holes for mounting the fan, secure the insulating
gasket (for Т, TH, VT, VTH and T1 models);
5. Route the power cable into the fan casing through the cable gland and secure the fan.
Dowels and screws are designed for concrete and brick walls. If the walls are made of the other material (drywall,
wood,etc.), use the fasteners appropriate for these materials to fasten the fan (not supplied with the fan and must be
purchased separately).
6. For V model, connect the power cable to the terminal block, for Т, TH, VT, VTH and T1 models, remove the cover from the
control board and connect the power cable to the terminal block on the board according to the wiring diagram for
your fan model;
7. Reinstall the control board cover, configure the fan operating modes by turning the potentiometers on the control board
using a special plastic screwdriver;
8. Reinstall the front panel of the fan;
9. Supply power voltage to the fan.

FAN OPTIONS
V— the fan is turned on and off with a pull cord switch.
VT — the fan is equipped with a turn-off delay timer. Starts running when turned on using the pull cord switch. Upon
turning off using the pull cord switch, the fan continues to run for the time set on the turn-off delay timer.
VTH — the fan is equipped with a humidity sensor and a turn-off delay timer. Starts running when turned on using the pull
cord switch. Upon turning off using the pull cord switch, the fan continues to run for the time set on the turn-off delay timer.
If the ambient humidity exceeds the threshold set by the control potentiometer, the fan starts to run. After the humidity
drops below the set threshold, the fan will continue to run for the time set by the turn-off delay time.
T— the fan is equipped with a turn-off delay timer. The fan starts to run when the input terminal LT is energised by an
external switch (e.g. when the room lights are switched on). Upon control voltage removal the fan continues to run for the
period set by the timer.
T1 — the fan is equipped with a turn-on and turn-off delay timer. When the input terminal LT is energised by an external
switch (e.g. switching on the room lights), the turn-on delay timer (0 to 2 minutes) is activated. After the turn-on delay time
has elapsed, the fan starts to run. Upon control voltage removal the fan continues to operate for the period of time set by
the turn-off delay timer.
If the control voltage is removed (e.g. by switching off the room lights) while the turn-on delay timer is active, the fan will
remain turned off.
TH — the fan is equipped with a humidity sensor and a turn-off delay timer. The fan starts to run when the input terminal LT is
energised by an external switch (e.g. when the room lights are switched on). Upon control voltage removal the fan continues
to run for the period set by the timer. If the ambient humidity exceeds the threshold set by the control potentiometer, the
fan starts to run automatically. After the humidity drops below the set threshold, the fan will continue to run for the time set
by the turn-off delay time.
